Data quality in EIONET: Summary

• Data quality in EIONET needs:– Continuous improvement– More documentation– More visibility

• Topic-specific QA/QC procedureshave to be embedded into a data quality management framework.

• The overall aim is (preferably) quantitative data quality reporting which is regularly updated in order to show trends over time.

• EIONET data quality reporting (mainly targeted at data providers, i.e. Countries) has to be complemented by data quality information targeted at end-users of the data.
